By Lee Chi-dong WASHINGTON, May 1 (Yonhap) -- Former U.S. President Jimmy Carter may soon travel to North Korea as part of his efforts, not always fruitful, to broker the resumption of dialogue and win the release of a Korean-American man detained there, diplomatic sources said Wednesday.

But the South Korean and U.S. governments apparently take a dim view of Carter's possible trip to North Korea out of concern that the communist nation may try to exploit it for propaganda purposes.
